DISCHARGING MECHANISM FOR SYRUP OR OTHER JARS.

SPECIFICATION forming part Of Letters Patent No. 642,1 19, dated January30, 1900.

Application filed April 23,1898. Serial No. 678i663. (No modeLl To allwhom, it may concern:

Be it known that 1, Isaac W. IIEYSINGER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have made a certain new and useful Improvement inDiecharging Mechanism for Syrup or other Jars and the Like, of which thetollowingis a full, clear, and exact description, referencebeing had tothe drawings which accompany and form a part of this specification, inwhich- Figure 1 is a vertical section from front to rear through themiddle of a syrup-jar em- Figs. 1, 1, and 1 are enlarged views showingslight mechanical modifications in the drip-stops which I prefer to use.Fig. 2 is a horizontal section along the dotted line a: as of Fig. 1looking downward on the bottom of the jar. Fig. 3 is a transversevertical section along the dotted line y y of Fig. 1. Fig. 4 is a view,similar to Fig. 1, of the operative parts of my invention, showing aslightly-differentarrangement of the discharge-pipe D and in which apositive instead of a spring thrust causes the retraction of the pistonor plunger within the force-chamber. Fig. 5 is a view similar to Fig. 4,in which instead of a push-button merely a lever-handle is used to forcedown the plunger and retract the same. Fig. 6 is a view similar to Fig.1, in which instead of a force-chamber of cylindrical form a softrubberhemisphere or the like open beneath is used and a plunger above it tocompress the same. Fig. 7 is a view similar to Fig. 1, in which theplunger is made solid and the vent-pipe for the syrup is carried fromthe force-chamber independently of the plunger and stem; and Fig. 8shows my invention in which the jar is mounted upon skids instead ofhaving side supports integral with the said jar and in use in asoda-water apparatus.

The lettering in all the figures is uniform. Myinvention relates tomechanism for the discharge of syrups or the like from stationary jarsor other receptacles into glasses or other vessels, as is customary insoda-Water apparatus; and it consists in forming the jar or receptaclesolid-that is to say, with closed sides and-bottom and without anysyrup-vent beneath-and in raising the syrup by pressure above the top ofthe jar and thence discharging the same into tumblers or the like, asmaybe desired; and it consists in provid ing such solidly-walled jarwith a recess in the bottom thereof to form a collecting cavity andhaving preferably sloping sides and providing for this recess anadjustable forcingchamber and plunger so constructed that when slightlyraised the syrup will flow into said collecting cavity or recess beneaththe sides of said forcing-chamber contained therein, and when the saidplunger is forced down contact will be first made between the margins ofsaid chamber and the bottom of said recess, and as the descent of thehandle and plunger continues the fluid contained in said chamber will beforced upward through a suitable tube provided therefor and over theupper margin of said syrup or other jarthat is, above the level of thefluid contained therein--and, when the plunger is raised again, that, atthe same time the margins of said chamber will be lifted from the bottomof said recess, and the same will refill so long as any fluid remains insaid jar.

It will be seen that, in my invention, I use mechanism which willcollect into a recess a limited supply of syrup from the jar, and inthis l provide a forcing-chamber open below and a pl uuger, so thatI canclose thereby connection between the mass of syrup in the said jar andthe limited quantity held in said forcing-chamber, and I then force thesame by pressure applied to said plunger through a suitable exit-pipe upand over the upper margin of said jar or above the level of the fluidcontained therein, the size of the forcingchamber thus graduating thequantity to be forced out at each reciprocation of said plunger, whichenables the syrup to bc accurately measured as it is drawn.

Anotheradvantage is that there are no cocks or faucets to become leakyat the bottom of the jar, so as to waste the syrup or else flood thecounter with syrup accidentally leaking from an unclosed faucet, whileby the use of my invention I am enabled to place my syrupjars down atthe bottom of a soda-water apparatus, where they ought to be to receivethe full benefit of the ice, and the ice-space is correspondinglyenlarged by these jars being I 7 opening A, the whole top of the jarmaybe devices in general use.

In the ordinary soda-water apparatus as used in drug-stores, & the frontand bottom parts of the interior are absolutely use-.

less, being a mere vacant space beneath the elevated row'of syrup-jars,and this becomes not only a waster of ice, but a source of dampness anddirt. f I

In my invention the row of jars rests practically atthe level ofthecounter upon which the apparatus stands, withonly enough spacebeneath to insure non-conduction of heat.

My invention also relates to devices for preventing drip after a glassof syrup has been drawn and to prevent ingress of insects or dirt to thenozzle thereof.

Referring to, the drawings, A, Fig. 1, is a rectangular jar longer fromfront to rear,

. though the shape is not material, and constructed ofglass,porcelain-lined metal, or the l a like and having an opening in the top,(shown at A, Fig. 1,) the remainder of the jar having closed wallsthroughout. Instead of this I left open, of course provided a largercover be used but I prefer for con venience in handling to haveitin theform shown. A's'shown at B, Figs. 1 and 3, in the forward side of thebottom I form a recess A, preferably circular in form, as shown at Fig.2,;and withinwardlysloping sides from above downward. The bottom'of thejar A, Figs. 1, 6, and 7, I also. slightly incline forward, so as.to-insure the drainage of the syrup into the recess A when thejar isnearly empty. To support the jar,

byreason of this recess A, I provide it with.

- side extensions B B, by means of which the jar willstand erect or mayhe slid in or out of its receptacle in a soda-water apparatus. In Fig.

8 instead of these side extensions of the jar I show skids B B,attached'to the syrup-jar holder of the soda-water apparatus, and inthis figure I show two of these jars in place, which skids sustain thejars in position therein. When what are called tipping jars areused---that is to say, jars which tip forward a at the top to be filledwithout removal from the apparatus-I prefer to use-the form of jarsshown in Fig.8, but-with the skids B" B replaced by the socketed frontsupport B, as shown in Fig. 5, whereby the jar can be tilted forward atits upper part, so as to expose the top of the, jar and permit theremoval of the discharging mechanism and refill the jar while stilljnplacein the apparatus, ,the proportions; being suitably conformedthereto, as

' with the present covers oftipping jars.

The opening A, Fig. 3, of the jar A is closed by the detachable cover C,which may be of wood, vulcanite, or metal As shown in Fig.

- 3, it has small flanged lips c c, which'secnre it in place, and, asshown in Fig. 6, it may be circular, if desired, and screwed fast intothe opening A the same then being also circular and screw-threaded.Ordinarily I hold it in makes a sealed joint to prevent'egress of thecontained fluid. 1 When raised slightly, the fluid again flows in fromthe jar and fills this recess and the cup or chamber. -As shown inFig.1, this cylindrical forcing chamber or cup F is covered over abovewith theperforated cover pierced with exit-holes ff to permit the fluidabove the plunger tofiow out when the said plunger has been raised. Theplunger D fits this forcing-cylinder'likea piston and at its middle hasa hole which discharge-pipe D, rigidly secured thereto, so

down and the plunger then descends the con tained fluid will be forcedupward through margin of the jar A to its discharge-exit D, where it maybe caught in a tumbler placed glnderneath and adjacent to the face ofsaid ar. 1 v v To insure the consecutive movements of the plungerv andforcing-chamber, I provide the handle Eat the top of the stem E", whichpasses down vertically to the plunger D to ,which it is attached. Acoiled spring E, Figs. "11, 6, and7, maintains this handle in anelevated position, so as to hold up" the bottom margins of theforcing-chamber F from contact with't'he recess A. A coiled spring Dbeneath the cover 0 bears beneath upon the collar F of the forcing cupor chamber F and above "against a collar d upon the plungerretracted tothe upper part of the chamber F except when forced down against thetension of this spring D by pressure'npon the handle top ofthe-forcing-chamber F and at their upper ends passing throughperforations in the ment of the plunger D to carry down the jointbetween the plunger D and the neck F of the forcing-chamber F, as shownin Fig. 5. These rods are lettered D D and are .provided with collars d(1 Figs. '4 and 5, which may be made vertically adjustable, if desired.These collars d ,,striking against the under side of the cover 0, arrestthe upward motion of the forcing-chamberat a proper height, while thespring E continues the ascent of the plunger D in the chamber F.

else in contact with its sloping sides andv that when. theforcing-chamber is pressed opens into and forms the inlet of a verticalthepipe D' and thence outwardly over the IIO stem D E, sothat theplunger D is constantly -E. In Figs. 4 and 5 instead ofthe spring D' ,Iuse one or two rods attached below to the cover 0, and to enablethedownward move- 1 forcing-chamber F, I make a sliding friction- 1 InFig. 5 instead or using the coiled spring E, I operate the tube D bymeans of a pivoted lever E pivoted to D at e and to the cover at C, anduse the hinge-spring E to hold the lever-handle E elevated againstpressure.

The inside of the collar F, as shown at Fig. 2, I prefer to make, whenthick syrups are used, with vertical flanges around the tube D toprevent sticking from crystallization of the syrup. The lever-handle E E(shown in Fig. 5) may be used with the devices shown in all the otherfigures, if desired.

In Fig. 6 instead of a rigid forcing-chamber F, I use a collapsibleelastic rubber cup F, open beneath, perforated at its center for thedischarge-pipe D, and secured to the; lower end of the same. Above it isthe flat plunger or rigid portion F, the purpose of which is to compressthe top of the pressure-chamber and so eject the fluid through the tubeD and the discharge-nozzle D.

In Fig. 7 I use a mechanism similar to that shown in Fig. 1, except thatthe plunger-stem E is solid, the plunger D is without a perforation, andthe dischargc -pipe' D is carried up directly from the bottom of therecess A,

so that it does not rise and fall with the movements of the plunger, butis fixed with reference to the jar A. The springs E and D" have the samefunctions as in Fig. 1.

In Figs. 1, 1", and 1 I show the means which I prefer to use to preventdrip from the discharge-nozzle D or the entrance of insects or dirtthereto. In Fig. 1 is shown a cylindrical plug E, which occupies thebore of the tube D and reciprocates therein across thedischarge-openingD It is connected with an arm E, which is pivoted at C by means of thepivot e to the top of the fixed cover, so that as the handle E isdepressed, carrying with'it vertically the tube D, the arm E will thrustforward the sliding plug E within the tube D and uncover the vent D Whenthe handle E again rises, it will draw back the plug E over the vent Dand again close the same. In Fig. 1" the same devices areshown,excepting that instead of an internal plug E an external sleeve E isused, which opens and closes the exit-opening D in the same manner.

In Fig. 1 an internal plug E is employed, as in Fig. 1"; but this isconnected to astem E, supported by acoiled spring a, and the inwardforce of the fluid compresses this spring and opens the vent, whichagain closes when pressure has been removed from the handle E. The formshown in Fig. 1 is especially adapted for use with the modificationshown in Fig. 7.

In Fig. 1 I have indicated the use of the form shown in Fig. 1.

While I show these various devices hereinabove described as in usetogether in my improved discharging mechanism for syrupjars and thelike, I do not always use all these devices together, and I also varythe same to conform to special applications and requirements as would bedone to meet such conditions by any skilled mechanic and withoutdeparting from the principles ofv my invention as herein shown,described, and claimed.
